Definition of target antigens for naturally occurring CD4+ CD25+ regulatory T cells
The antigenic targets recognized by naturally occurring CD4(+) CD25(+) regulatory T cells (T reg cells) have been elusive. We have serologically defined a series of broadly expressed self-antigens derived from chemically induced mouse sarcomas by serological identification of antigens by recombinant expression cloning (SEREX). CD4(+) CD25(+) T cells from mice immunized with SEREX-defined self-a...
متن کاملInterleukin-37 Enhances the Suppressive Activity of Naturally Occurring CD4+CD25+ Regulatory T Cells
Naturally occurring CD4+CD25+ regulatory T cells (Tregs) are essential for the suppression of autoimmunity and can control the immune-mediated pathology during the early phase of sepsis. Our previous data showed that silencing interleukin-37 (IL-37) in human CD4+CD25+ Tregs obviously reduced the suppressive activity of CD4+CD25+ Tregs. Here, we found that rhIL-37 stimulation markedly enhanced t...
متن کاملSelective survival of naturally occurring human CD4+CD25+Foxp3+ regulatory T cells cultured with rapamycin.
Naturally occurring CD4(+)CD25(+) regulatory T (nTreg) cells are essential for maintaining T cell tolerance to self Ags. We show that discrimination of human Treg from effector CD4(+)CD25(+) non-nTreg cells and their selective survival and proliferation can now be achieved using rapamycin (sirolimus). Human purified CD4(+)CD25(high) T cell subsets stimulated via TCR and CD28 or by IL-2 survived...
متن کاملThe phenotypic characterization of naturally occurring regulatory CD4+CD25+ T cells.
The homeostasis of the immune system depends on the balance between the immune response to an invaded pathogen and the immune tolerance to self antigens. Both central and peripheral tolerances are important mechanisms for the induction and maintenance of T cell tolerance. Recently, much attention has been paid to regulatory T cells (Treg), which play a significant role in maintaining peripheral...
متن کاملRole of naturally occurring CD4+ CD25+ regulatory T cells in experimental atherosclerosis.
OBJECTIVE Naturally occurring CD4+ CD25+ regulatory T cells (Tregs) exert suppressive effects on effector CD4 cells and downregulate experimental autoimmune disorders. We investigated the importance and potential role of Tregs in murine atherogenesis. METHODS AND RESULTS Tregs were investigated comparatively between aged and young apolipoprotein E-knockout (ApoE-KO) mice and age-matched C57BL...
